Answer:
12.3 months
Step-by-step explanation:
You want the number of months (m) such that ...
1 - 17% = (1 -1.5%)^m
Taking logarithms:
log(0.83) = m·log(0.985)
m = log(0.83)/log(0.985) ≈ 12.3 . . . . months
Answer:
1.)616 in
2.)260 ft
3.) 744 mm
Step-by-step explanation:
4/10 = 40/100

Answer:
y = 2x - 3
Step-by-step explanation:
The 99 percent confidence interval for the true mean length of the bolt is CI = (2.8712, 3.1288)
<h3>How to find the confidence interval?</h3>
Confidence Interval is used to tell us the degree of certainty or uncertainty that is existent in a sampling method.
The general formula for confidence interval is;
CI = x' ± z(s/√n)
where;
x' is sample mean
z is z-score at confidence level
s is sample standard deviation
n is sample size
We are given;
sample size; n = 36
Sample mean; x' = 3 inches
standard deviation; s = 0.3 inches
confidence level = 99%
z at 99% CL = 2.576
Thus;
CI = 3 ± 2.576(0.3/√36)
CI = 3 ± 0.1288
CI = (2.8712, 3.1288)
